The W32.Perrun virus

June 14, 2002Over the years we've seen several warnings for JPEG viruses that turned out to be hoaxes of April fool jokes. This time however, the new W32.Perrun virus appears to be the real thing. The virus infects JPEG files, but the malicious content of files that it infects will not spread to other computers. Indications of infection are that .jpg files have increased in size by approximately 11KB, and the presence of a file named: Extrk.exe.Virus definitions updates for the W32.Perrun virus are available by now from the Antivirus Software providers.
